Software development

I develop software since 1999 and I have a Diploma in computer science. I focus on web and smartphone applications. I am running a small business since 2010.

Media design

The design of a website, the user interface of an application—the first impression counts. Let me design your user interface or your print product.

Net politics

I am politically active and deal with topics related to Internet policy, data privacy and data protection. I comment on technical backgrounds of political decisions.

Hi, I am Henning Tillmann.

Allow me to introduce myself.

  • Berlin and Kamen

    I was born in 1985 and I grew up in Kamen in Westphalia, Germany. I am currently living in Berlin-Friedrichshain.

  • Computer science

    I studied at the Technische Universität Dortmund and at the Humboldt-Universität zu Berlin. I have got a diploma in computer science (final degree: “very good”). I did a research study on browser fingerprinting.

  • Software development

    At the age of 13 I started to become interested in software development. At the age of 15 I created the first website for a client and developed an ActiveX component, that was voted best code of the month on Planet Source Code. Since then, I am fascinated by programming and designing software.

  • Political activities

    I am a member of the Social Democratic Party of Germany (SPD) and the committee for media and net politics of the SPD party executive. I am also member of the board of D64 – Zentrum für digitalen Fortschritt and specialize on digital education and data policies.

My portfolio.

This is a small and incomplete overview of software projects and media products I have created.

I published a research paper on browser fingerprinting.
The paper and additional information can be found here.

My blog.

Sorry, my blog is available in German only.

I look forward to hearing from you!
